Hi Jill Griggs,
Thank you for the update. For this specific requirement, we recommend using a custom toolbar for the PDF Viewer instead of the default toolbar. This approach allows complete customization of the toolbar by directly utilizing the Syncfusion Toolbar within the application project.
We have attached a sample project for your reference. Please review it and let us know whether it meets your requirements or if you have any questions.
